The longevity of any flooring is directly tied to the subfloor. If the subfloor is uneven, high spots can cause stress on plank locking systems, leading to separation. If there is residual moisture, it can cause warping or mold growth in the flooring above. A proper subfloor check involves verifying moisture levels, ensuring the surface is level within manufacturer tolerances, and removing debris or old adhesives. Skipping these steps significantly reduces the service life of your new floors.
